Each guide answers one question. Optical computing and optical networking are kept in separate sections because a faster link is not the same thing as a calculation done with light.
Optical computing
- What is an optical processing unit?
Understand what an OPU calculates, how light represents data, and where a photonic accelerator fits beside conventional computing.
- How photonic computing performs a calculation
Follow a worked optical weighted sum from input encoding to detection, then compare intensity-based and coherent photonic designs.
- Photonic accelerators versus GPUs: workloads and trade-offs
Compare photonic accelerators and GPUs by supported operations, precision, data movement, and complete application performance.
- The practical limitations of optical computing
See which limits come from noise, conversion, programming, and the rest of the system, and which comparisons leave those costs out.
- How to evaluate photonic-computing performance claims
Read optical-computing benchmarks with a practical checklist for workload, precision, latency, power boundaries, and measured versus projected results.
Cloud infrastructure
- Optical processors versus optical interconnects
Separate computing with light from moving data with light, and learn how to read photonics announcements without confusing the two.
- Co-packaged optics, optical I/O, and pluggable transceivers
Understand where optical conversion happens, why packaging matters, and which serviceability and power questions to ask about data-centre optics.
- Where photonics fits in an AI data centre
Map photonics across AI infrastructure, from fibre networks and optical I/O to experimental compute accelerators, using a simple bottleneck example.
